Several 1-3 ft. stems emerge in a clump from the woody root of Tall Fringe Bluebells or Mountain Bluebells. Smooth, succulent leaves are crowded along these stems. A plant with clumps of leafy stems and loose clusters of narrowly bell-shaped, blue flowers turning pink with age. Pendent clusters of clear blue, tubular flowers exude a mild fragrance. Root crowns and rhizomes spread over time, forming extensive patches.

Mertensias are also called Lungworts, after a European species with spotted leaves which was believed to be a remedy for lung disease. Similar species differ in the proportions of the corolla.
